Description

          Just a random note on this: I agree that having SpatialData - level attributes would be super helpful. Beyond that, I think it would be great to be able to annotate coordinate systems - these often correspond to samples, conditions, time-points etc. I can of course annotate all elements within a coordinate system through tables, but I think it would be more direct to somehow directly provide metadata for an entire coordinate system.

Research direction

Start by reading the original discussion in issue #711, especially the linked comment, to understand the proposed SpatialData-level attributes and coordinate-system annotations. The scope, API location, and acceptance criteria are not defined here; done would require an agreed design for attaching metadata to an entire coordinate system.
